Too bad that you did not pick up the Hodgdon powder instead.

It is the powder ment for reduced loads.............
and there is lots of data out there for many calibers.

IMR is a good powder for light target loads but not real light "Reduced loads".

In my 30-06 with a 150 ball with IMR I can get a nice target load at 2590fps.

In my 22-250 a 55 gr fmj with IMR 4895 at 2996fps works for me.
